Keep every vessel ready for service.

Bring maintenance, defects, compliance and operational information together so technical teams stay in control without adding more administration.

Keep the work moving. Keep vessels ready.

One connected platform for maintenance, defects, logs, forms and inventory. Crews see their daily work; shore teams see what they need to support reliable service.

Built for ferries, passenger vessels, workboats and commercial fleets.

Commercial Vessel Maintenance Software

Simple onboard. Clear ashore.

Six areas of work, one record shared by the vessel and the office.

Planned and corrective maintenance

  • Calendar, running-hour and condition-based schedules
  • Corrective jobs raised from defects and inspections
  • Due, overdue and upcoming work across the fleet

Defect management

  • Raised onboard with detail and photographs
  • Tracked by severity and owner through to close-out
  • History kept against each component

Compliance, forms and logs

  • Digital logs, checklists and operational forms
  • Records ready for inspections, surveys and audits
  • Certificates and expiry dates tracked per vessel

Inventory, spares and documents

  • Spares and consumables by vessel and store
  • Critical spares visible before a job starts
  • Manuals and drawings filed against the equipment

Vessel-to-shore reporting

  • Outstanding work visible without chasing updates
  • One record shared by the vessel and the office
  • Reports that reflect the work actually completed

Fleet oversight and performance

  • Maintenance, defects and compliance compared across vessels
  • Machinery condition reviewed with operational data
  • Fuel and energy use alongside speed and conditions

Predictive Maintenance for Commercial Fleets

From vessel data to earlier maintenance action

Mariners Log reads the machinery, maintenance and operational data your fleet already produces and flags conditions that are changing. Teams hear about a developing problem as an alert, not as a failure in service.
